Reducing the Amount of Waste Generated
Basic Approach
In working towards creating a recycling-minded society, we have adopted a basic 3R policy (reduce, reuse and recycle) and in aiming for an even higher level of 3R achievement, we encourage all our employees to separate waste materials into diff erent categories for more effective recycling.
Fiscal 2007 Performance
In the Stage IV Environmental Protection Program, we set the goal of reducing the amount of waste generated by our business operations by 3% compared to fiscal 2005 levels by the end of fiscal 2009.
The total amount of waste generated by the Fujitsu Group came to 33,947 tons in fiscal 2007. While the results for the previous fiscal year corresponded to a 2.5% decrease, they corresponded to a 2.4% increase compared to fiscal 2005. This increase was due to increased production of semiconductors.
Effort to Recycle Fluorite
While hydrofluoric acid is indispensable in semiconductor manufacturing, it also generates large amounts of sludge in effl
uent wastewater processing. At the Fujitsu Microelectronics, Ltd. Mie plant, we succeeded in creating and recovering high
purity fl uorite from wastewater with high concentrations of hydrofl uoric acid by adopting a revolutionary new technology.
This new technology allowed us to reduce the amount of sludge generated by about 40%.
Furthermore the recovered fl uorite can be used as a raw material for making hydrofl uoric acid.
Biodiesel Fuel Reactor
PFU Ltd. installed a BioDiesel Fuel (BDF) reactor to refine waste cooking oil from the company cafeteria into biodiesel fuel for PFU-owned trucks, both to reduce waste and to replace the petroleum-based fuel that would otherwise be used.
